Test
To Set the PN Scanner Sensitivity:
Setting Average, Sweep, and Restart
Setting the Sweep
You can select either continuous or single sweep. Continuous sweep provides
repeated, ongoing measurements. Single sweep performs a single measurement that
is repeated only when you push the Single button.
To set sweep:
Setting Averaging
You can choose to have averaging On or Off, and to set the number of averages you
want to take. When initialized, the Agilent E7495A/B defaults to running average:
• A running average computes the new result as the weighted sum of the last result
and the new measurement. The last result is weighted by (n – 1)/n. The new
result is weighted by 1/n. Each new measurement produces a new result.
The reported averages for the following measurements will only be updated when
idle slots are identified within the update interval. If no idle slots are identified, the
average values reported will be from the previous update interval:
• Idle Power
• On/Off Ratio
• Noise Floor
